How Recent Changes in Country Conditions Can Affect the Relevance of Earlier Expert Evidence

Country conditions can change over time. Political developments, changes in government policy, conflict, security conditions, restrictions affecting particular groups, and other developments may alter the factual context relevant to an immigration or asylum case.

For solicitors working with an immigration expert witness, this can raise a practical question: does an earlier expert report still address the country conditions relevant to the case, or should more recent information also be considered?

The answer will depend on the circumstances of the case, the subject of the original report, the date and scope of the research, and the nature of any subsequent developments. An older report is not necessarily irrelevant simply because it was prepared some time ago. Equally, a significant change in circumstances may mean that its analysis should be considered alongside newer material.

This article outlines some practical considerations when assessing the continuing relevance of earlier country expert evidence.

Why the Date of an Expert Report Can Matter

An expert report is generally prepared with reference to information available at a particular point in time. It may therefore describe country conditions as they existed when the expert conducted their research and formed their opinion.

The passage of time does not automatically make an expert report irrelevant. However, the date of the research and the period covered by the report can be relevant when considering whether it addresses the circumstances under consideration.

Potential developments may include:

• A change of government or political administration
• Changes to legislation or official policy
• New restrictions affecting a particular group
• Changes in conflict or security conditions
• Developments affecting freedom of movement
• Changes in the treatment of particular political, religious, ethnic or social groups
• Developments concerning access to state protection
• Changes affecting conditions in a particular region

The significance of any development will depend on the issues addressed by the expert evidence.

When Later Developments May Be Relevant

Not every change in a country will be relevant to every immigration or asylum case. A useful starting point is to identify the factual questions addressed by the earlier report.

Changes Affecting the Subject of the Report

An earlier report may focus on a particular group, region, institution or form of risk. If circumstances concerning that subject have subsequently changed, newer evidence may warrant consideration.

For example, an expert report examining conditions affecting a particular minority group may have been prepared before a significant political or legislative development concerning that group.

In such circumstances, the later development may be relevant to the factual background considered by the decision-maker.

Changes Affecting a Particular Region

Country conditions can vary between regions. An earlier report may contain analysis of conditions in a particular city, province or area.

If significant developments have subsequently occurred in that location, it may be useful to consider whether the earlier geographical analysis remains applicable to the period under consideration.

This may be particularly relevant where the evidence concerns return to a specific location or conditions elsewhere within the country.

Changes in Law or Official Policy

Changes in legislation, government policy or administrative practice may also affect the factual context.

An expert can provide evidence about relevant country conditions within their area of expertise. The legal significance of those conditions remains a matter for the relevant decision-maker.

It is therefore useful to distinguish between evidence about developments in a country and legal submissions concerning how that evidence should be considered in an individual case.

Reviewing an Earlier Country Expert Report

Before considering whether further expert evidence may be useful, solicitors may wish to review the earlier report carefully.

Check the Period Covered by the Research

The date of publication is only one consideration. It may also be useful to identify the period covered by the expert's research and the dates of important sources relied upon in the report.

An older report may contain analysis that remains relevant to a particular historical period. Conversely, a more recent report may still rely substantially on information relating to earlier events.

The key consideration is whether the evidence addresses the period and factual questions relevant to the case.

Identify the Questions the Expert Addressed

The continuing relevance of an expert report may depend partly on what the expert was originally asked to address.

Consider whether the report dealt with:

• General country conditions
• Conditions affecting a particular group
• Conditions in a specific geographical area
• Treatment by state authorities
• Access to state protection
• Internal relocation
• Social or cultural factors
• Linguistic or identity issues
• A particular historical period

This can help distinguish information that may remain relevant from matters that may require more recent consideration.

Review the Sources and Subsequent Developments

The sources cited in an expert report can help establish the period and scope of the evidence.

Where significant developments have occurred since the report was prepared, it may be appropriate to consider whether relevant and identifiable newer source material has emerged and whether it affects the factual questions addressed by the earlier report.

The purpose is not simply to replace older sources because they are dated. Rather, the question is whether the existing evidence, considered as a whole, addresses the circumstances that are relevant to the case.

What Further Expert Evidence May Add

Where country conditions have changed, further expert evidence may, depending on the circumstances, provide an updated assessment within the expert's area of expertise.

Depending on the instructions and issues involved, an expert may be asked to consider:

• Developments since the earlier report
• Changes affecting a particular group
• Changes within a particular region
• Changes in government policy or practice
• Whether particular earlier observations remain applicable
• New source material relevant to the questions being addressed
• The distinction between continuing conditions and subsequent developments

Any opinion provided should remain within the expert's expertise and be supported by relevant source material.

A later report does not necessarily need to repeat every aspect of an earlier report. Depending on the circumstances, its purpose may instead be to identify relevant developments and explain their significance within the scope of the expert's expertise.

Keeping Expert Evidence Separate From Legal Submissions

Country expert evidence and legal submissions have different functions.

An expert may provide specialist evidence about matters within their expertise, including country conditions and developments that may not be readily apparent from general country information.

The solicitor or advocate can then make the relevant legal submissions about how that evidence should be considered within the applicable legal framework.

Keeping these roles distinct can help make it clearer which matters are being presented as expert evidence and which are legal arguments.

Reviewing Country Evidence Before a Hearing

The continuing relevance of an earlier expert report can become an issue where a substantial period has passed between preparation of the report and a hearing.

A solicitor may wish to consider:

1. When the expert conducted the relevant research
2. Which period the report covers
3. Whether significant developments have occurred since the research was undertaken
4. Whether those developments relate to the issues addressed by the report
5. Whether relevant newer country information is available
6. Whether further expert consideration may be appropriate within the expert's field
7. Whether the existing report clearly distinguishes historical conditions from subsequent developments

These considerations do not determine whether further expert evidence is required. They can, however, help identify questions that may warrant closer review.

Changes in Country Conditions Do Not Automatically Make Earlier Evidence Irrelevant

It is important not to treat the age of a report as the sole measure of its relevance.

An earlier country expert report may have been prepared to address historical conditions, events or circumstances that remain important to the case. In other situations, subsequent developments may have a more direct bearing on the issues considered by the expert.

The appropriate approach will depend on the subject matter of the report, the period covered by its research, the nature of subsequent developments and the questions that the decision-maker needs to consider.

Conclusion

Changes in country conditions can affect how earlier immigration expert evidence should be considered, but their significance will depend on the circumstances of the individual case.

For solicitors, reviewing the scope and research period of an earlier report, the sources relied upon and any significant subsequent developments can help identify whether the existing evidence remains relevant to the questions at issue.

Where newer developments are material, updated country information or further expert consideration may be worth considering within the appropriate scope of the evidence. Any expert opinion should remain independent, appropriately supported and within the expert's area of expertise.
